Lachie Gillespie [to replace Fatt as the next purple Wiggle] is very laid-back and much like myself.

"He'll become 'Wake Up, Lachie' to replace 'Wake Up, Jeff'. What we have had is too wonderful to let go," said Fatt.

After a life of stardom, Mr Fatt is still a child of the Northern Rivers.

"My family go to Ballina for Christmas and we have our holidays there. I usually make a day trip to Casino," he said.

Looking back over his career, Mr Fatt says one of the biggest highlights was performing at New York's Beacon Theatre on a night when Robert de Niro, Jerry Seinfeld and Lynn Redgrave were in the audience.

After the tour winds up, Mr Fatt will go on writing and recording material for the new Wiggles.

Asked the secret of The Wiggles' success, Mr Fatt said there was no formula.

"When Anthony asked me to get involved in the first Wiggles recording, I never thought it would go much further," he said.

"There is no business plan for this sort of thing. It's something that just happened."
